I stand behind Aaron and his products 110%, day in and day out. I've been using their sysem since September and would never go back. I've never had a pad fly off, never pressed so hard that the adapter poked through (I don't hold the pad
that flat to begin with). The only problem I've had with one of my pads was that the hole rounded out from so much use. But by then, the pad was more or less toasted anyway.
The great thing I like about their system is not only the ease of changing pads, but the feel I get while using a buffer. When I used velcro pads I could never seem to get the pad "just right", I always had a slight vibration. With the Edge system I get a much more positive feel while buffing, with the now even shorter rotary adapter I think any pad hopping has been eliminated.
We can't forget the HUGE line of pads that they offer. I've got wool, foam, and waffle foam pads and have zero complaints about any of them. My favorite ones are my waffle pads, I've fallen in love with the blue pad

They're cheaper than buying two one sided pads, they're durable, Aaron provides oustanding customer service, and I overall just like 'em :rockon
